PICKER-CHECK.

Specification of Letters Patent.

Patented aan. 2,1912.

To all 'whom it may concern:

Be it known vthat I, CHARLES N. TUCKER,

-a citizen of the United States, residing at Pawtucket, in the 'countyof Providence and State of Rhode slatd, have invented certainVImprovements in Picker- Checlis, of which the following is aspecification, reference being panying drawings.

This invention relates to improvementsin picker checks for looms, forchecking the motion of the picker staff at the extremities vvthe objectof the invention being to .provide a simple and eiicient decharacter,which ma be ad vary the extent of its check,-

4being to enable the heel strap to-be materif lower end ofthe Ais allyshortened so as to etlect an economy in the construction of the pickercheck and in the cost of maintaining the loom, another object being toprovidean improved device which prevents the heel strap from slipping4from and becoming disconnected from the picker statt.

Another object of the invention is to provide an improved device .toprevent the picker stad from jumping up and becoming unseated from theshoe if the heel strap should break.

With the above `and other objects in view, my invention consists in theconstruction,

combination and arran ement of devices hereinafter described an claimed.Y In the accompanying drawings*Figure 1 an elevation of a picker staffprovided with my improved check and showing the same in connection withthe coacting parts o`fa loom. Figa 2 is a vertical sectional View on theplane indicated by the line aa of Fig. 1f F 3 is a horizontal sectionalview on the plane indicated by the line b'-b of Fi 1. Fig. 4 is asimilar View on theplane indicated by the line @-0 of Fig. 1. Fig. 5

' is' a detail transverse sectional view taken on the plane indicated bythe line d-d of Fig". 1.

I The picker stati' 1, swings upon the step 2, and o crates in the lay3. The rocking foot of t e stati has a vertical slot 5, which receives alug 6 that projects from the upper side ot the step. An ear 7 dependsfrom one side of the step and is provided with a horizontally disposedspindle 8 which extends had to the accomtransversely nnder the step andon which is mounted the roller 9 which is turned inone direction bya=spring 10, All of these parts are of theusual construction.

One end of the heel strap 11 is attached to the roller 9. In accordancewith my invention, the opposite end instead of being attached directlytothe lower end of the picker stati' as has heretofore lusually beendone, is attached as by means of av suitable lbelt hook to a transof theheel strap verse hook 12 at the lower end of a hook rod 13. The hook 12extends under the step. The upper end of the rod has a laterallyextending portion 14 which has a. U-shaped upwardly extending arm 15which bears against the inner side of the picker statt and is securedthereto by means of a bolt 16 and a clip shaped washer 17, the said boltextending throu hthe washer, opel ating in the slot forme by the arm 15and being engaged by a nutv 18 which bears on the outer side of thewasher and coacts with the washer to clamp the arm 15 between the washerand the picker stati and to enable the saidfarm to be adjustedvertically so as to correspondingly adjust the said hook rod 13. Themajor portion of the hook rod eX- tends downwardly on one side ofthepicker staff, and also on one side of the foot 2, and the step.

A clip 19 is secured on the outer side of the picker staff, the bolt andalso the upwardly extending portion of the foot. A washer 21 on the saidbolt is interposed between the picker staff and the clip. The clip hasan outwardly extending arm or wing 22, which extends behind the hook rod13. The picker stati is slidable to some extent in the usual opening 23,in t-he step 2. By first loosening the nut 18, on the bolt 1G, the rod13 may be raised or loweredA on the picker staff so as to vary thetension on the spring 10 as may be required according to the desiredcheck on the picker staff. To increase the check, the rod 13 is raised.To take oit or loosen the check, the said rod is lowered. Havingadjusted the rod 13 as required, the nut 18 is then tightened on thebolt 16, so as to cause the washer 17 to firmly grip Athe slotted arm 15of the rod, and secure the'said arm, and hence the rod in the requiredadjusted position on the picker staff.;

Since the rod 13 to which the heel strap is' connected is disposed onthe inner side of the picker staff, the heel strap is very much shorterthan hasheretofore been required, and enables a considerable economy tobe effected. Moreover, should. the heel strap break, another can bereadily substituted in its stead, and connected to the hook arm of therod 13, and without the necessity of removing any bolt or other likedevices, and Without the necessity of detaching the picker stad from therocking foot, as theheel strap in accordance with my invention,insteadof being connected tothe outside of the picker stai by the bolt 20, isconnected to the hook arm 12 of the rod 13. Furthermore, by connectingthe heel strap to the hook arm 12, the heel strap is e'ectuallyprevented from slipping from the picker staff, the clip 19 with its wing22 forms a guide for the hook rod 13, is not subject to wear, and'willlast indefinitely. Moreover my improved devices` cause the picker staffto throw the shuttle straighter than heretofore, prevent the pickerstaff from getting out of position and from getting out of order. i'

I claimt -v r1. In mechanism of the class described,

v the combination of a step, a picker stai? mounted thereon, a springactuated roller, and a rod attached to the sta', 'and having an armextending Itransversely under the step, and a heel strap attached to theroller and also attached to said arm.

2. A picker staii having an adjustable rod on one side thereof, andprovided with an arm to extend transversely under the step, and servefor the attachment of a heel strap.

3. A picker staff having an adjustable rod on one side thereof, andprovided with an arm to extend transversely under the step, and servefor the attachment of a heel strap, said arm of the rod forming a hookto prevent the picker stad from becoming unseated on the step in theevent of the breaking of the heel strap.

4'. A picker stai having a hook rod provided at its lower end with anarm to 'extend transversely under a step, and provided at its upper endwith an off-set vertically slotted arm to bear against one side of thestaff, in combinationwith a bolt extending through the stati and theslot of said arm, a clip on said bolt and bearings against said arm, anda nut on the bolt and -bearing against the outer side of the clip.

A5. A picker staff havin a hook rod provided at its lower end w1th anarm to extend transversely under a step, and provided at its upper endwith an oE-set vertically slotted arm to bear against one side of thestati', in combination with "a bolt extending through the staff and theslot ot said arm, a 'clip on said bolt and bearing against said arm, anda nut on the bolt bear'- ingagainst the outer side of the clip, the staibeing further provided wlth a gu1de clip attached thereto and providedwith an outstanding wing disposed at one s1de of the said rod.

In testimony whereof I hereunto aiiix my signature in the presence oftwo wltnesses.
